A portable smartphone laboratory that detects cancer!
In a major step towards faster and convenient delivery of medical tests, Washington State University researchers have developed a low-cost, portable laboratory on a smartphone that can analyse several samples at once to catch a cancer biomarker, producing lab quality results.

At a time when patients and medical professionals expect always faster results, researchers are trying to translate biodetection technologies used in laboratories to the field and clinic, so patients can get nearly instant diagnoses in a physician’s office, an ambulance or the emergency room. The research team created an eight channel smartphone spectrometer that can detect human interleukin-6 (IL-6), a known biomarker for lung, prostate, liver, breast and epithelial cancers. A spectrometer analyses the amount and type of chemicals in a sample by measuring the light spectrum. “The spectrometer would be especially useful in clinics and hospitals that have a large number of samples without on-site labs, or for doctors who practice abroad or in remote areas,” said lead researcher Lei Li, Assistant Professor in the School of Mechanical and Materials Engineering. “They can’t carry a whole lab with them. They need a portable and efficient device,” Li noted. Although smartphone spectrometers exist, they only monitor or measure a single sample at a time, making them inefficient for real world applications.
